When I was visiting kenpo schools last year, one that I visited had an instructor who taught a variety of systems. He said he taught Parker kenpo (turns out this was untrue) though he did teach the katas. Anyway, in talking with him he told me American kenpo is not a "complete" martial art because it fails to teach spiritual aspects of MA such as, moderation, living healthy, meditation, and things like that. In his opinion, it was all focused on the physical side of training and not on the spiritual side. He even when as far as to say most kenpo black belts are "adrenaline junkies" or alcoholics/drug users. Needless to say, I didn't go back for a second lesson. But I am curious, is his perspective of American kenpo and kenpoists shared by a majority of the traditional MA world?
